This invention relates to chair beds and in particular to one in which a f1'111 sized bed of maximum length can be folded.

A particular object of the inventin is to provide a bed structure that can be folded into a settee type chair in the lowest position consistent With comfortable use of the chair as such. The problem of providing a fu1l length bed structure that can 'be folded lengthwise f0r positioning in the bottom of a chair at the lowest poifit in volves the use 0f inner, middle anal unter sections that aie folded relatively 120 each other in the most compact manner possible anal which can be; by the folding Operation, lowered 130 seat in the bottom of the chair frame. The inventi0u also wntemplates ease of folding the sections by tha arrangement of the parts and connections thereof and provides for a longitudinal motion of the partly folded structure tha1; will automatically lower the folded assembly into platze in the bottom of the chair frame. It is a feature of the invention that the least number of parts are ernployed that are consistent with streng and dumble structure am} easy folding Operation, the arrangement ofthe parts being such that they fold compactly with a minirnum of preliminary adjustment, and when incorporated in the chair in folded positi0n conceal the fast that a bed is also part 0f the chair structure.

With these and other objects in view, the invention comprises certain constructions hereinafter described and then particularly pointec1 out in the clairns and a preferred form of my invention is illustrated inthe ac'companying drawings, in Which:

Figure 1 is a section in Side elevation taken through a chair frame and showing the bed structure in open position in fu1l side view,

Figure 2 is a similar view showing the bed structure in first fo1d position in ful1 lines ai1d second fold position in outline,

Figure 3 is a view similar to Figuire 1 showing the bed structi1re in a position it would assume during sliding and lowering movement to place it in the chair frame,

Figur 4 is a view similar to Figure 3, but showing th bed structure completely folded into the chair frame 110 provide a seat,

Figure 5 is a perspective view of a detail of thebed structure as viewed a1: the 1ine 5--5 011 Figure 2,

Figur 6 is a side view of an operating detail associated with a fo1d' sectionshbwn enlarged',

and

Figure 7 is a section an the line 'I1 of-Figure 6.

Referring 170 the drawings in detail, Hi indi--- cates chair ends shaped to provide arm and back parts H and. I2 mspectively, which are joined by suitable cross pieces I3 placed conveniently so give a substantial chair frame. The mat tress supporting frame cf the bedis made in the usual manner with L-shaped rails or bars between which is stretched the spring panel for holding the mabtress. The spring and rails are indicated by the numerals I 4 and I5 respectively and. the rails am]. spring assemblies are arranged provide the relatively foldable sections, progressing outwardly from the chair, identified as the inner section I, middle section I'I, fo1d sectiom I8 and outer section I. The inner frame section I 7 carriias corner foot-pieces 20 which are pivoted as ab 2! 110 brackets 22 secured to the chair ends 23, and theinner end of the section is reinforced by the cross bar 24. Both sides of-the bed=struc ture are identical and hence only one side will be referred 1:0, no p1an view beingdeemed. necessary as the art shows that the levers, legs and frames are suitably bent to clear each other in folding relation, and these structures and. their method cf assembly are weil known by those skilled in the art.

The middle section I i is pivoted as at 25 the section I6 and is supported in relatively swinging relation to the chair frame by the swing 1ever 25, hinged 120 the section I1 as at 27 and pivoted. so a frame p1ate 28 as at29. The 1ovver end of the 1ever 26 is connected by a spring 30 110 an ear 3l formed on said platze 28, ehe platze forming part 0f a reinforce structure for the chair anal including the cross braces 32 anal 33, which support the folded bed structure when it is compacted into the chair frame as sh0wn in Figure 4. -A stop 35 oh middle section fl'l also acts as a rest for the outer folded section as shown in Figures 2, 3 and 4-. The middle section I! is pivotally connected at its end With the outer section 19 through the medium of the fo=ld section I8, the pivot points being indicated as at 36 and 31, which permit the outer section to be folded parallel to the middle section H anci thereabove to provide a compact and sturdy seating struct-ure when the parts are folded into the chair frame.

One cf the feature;; o-f my invention is th arrangement cf the front chair pane1, strip and seat frame 011 the folding sections so that they will be folded intc) p1ace Without any attention on the part; of the operator and this end, the fo1d section 18 is provided With a depending fixed leg bracket 40 (Figures 6 and 7) to which the rear leg is eccentricelly pivoted es et 42, the leg 4I being pivoted es et 43 et .its upper end to the outer end of e reer leg lever 44 which is pivoted es et 45 to the middle section I'I, The fold section is reletively nerrower then the sections I'I end I9 which it joins end it bes pivoted thereto es et 46 e forwerdly extending front leg lever 41 which is pivoted es et 48 to th upper end of e front leg 49 pivoted es et 50 '00 the outer section I9. Both legs, I;he reer leg 4l end the fron1: leg 49 firmly support the extended portions of the bed structure when the seme ere open for bed use. 1 The oi1ter section I 9 supports, through e link 52,

The strip 54 endcomplished by the swinging of the inner section I6 ebout its supporting brecket 22 es et 2I.

The folded structure rests in the bottom of the cheir es shown in Figure 4 end the peres ere so lowered thet the seet cushion C is 10W end comfortebly positioned 150 permit the legs to rest comfortebly on the floor, this feeture removing one of the objections 110 the use, heretofom of sufficizgnt structura to meke e folding bed thet could be mede long enough to permit sleeping with the feet inwerdly of the cheir, sq thet two persons could find enough room in the bed end considerebly m0=re then could be effordecl by the prior strucbures thet mede sleeping lengthwise of the cheir necessery.

My improved folding bed structure cen be in.-

' corpoieted in eny suiteble cheir or teble freme the bed structurewhen the seme is folded into v the cheir'es sho'wn in Figure 4. The unter end oithe unter Secoion I9 (Figure 5) is closed by the cross brece 5'I, the seme being fixed to e corner piee 58 et eech end of section I9 to which is pivoted e heed piece freme 59. The heed piece comprises the pillow supporting strips 6I end 62, 120 the letter of which e spring is secwed 130 con nect the heed piece end the brece 5'l. The spring 63 acts to meintein the heed. rest struct1ire in either its open position esin Fig1ire 1 o1 in its folded positiom es et Figure 5 beceuse the side breckets 64 through Which the strips 6I end 62 ere pivoted with respectto section I9 es et 65 swing the spring 3 pest the pivot; center 65 whi zh joins the heed piecefreme 1:0 the corner piece 58. 9

A mettress M is indiceted in outline end Starting With the bed fully open es in Figure 1, the first folding movement results in the bed outer section I9 being lifted I lo the positiou in full lines in Figure 2. 'Ihis motion closes the front le end swings the seet frerne 53 ebout its hinge 55 until the strip 54 ishorizontel The second folding movement begin eutometicelly beceuse the fold of the leg 49 prevents further hinged movement of th outer section reletively 130 the fold section I8 end hence eontinued folding pressure on I:he outer section I9, results in the flding of the fold section I8 ebout the pivot 36 110 positin the perts es shown in outline in Figure 2 end until the corner piece 58 rests on the stop 35 through th e medium of engegement of shoulder 66 in piece 58 with the turned over top edge 01' end of the stop 35. This second foldingmovement eutometicelly ceuses the reer leg lever 44 to swing the reer leg 4! 130 e position parallel to the fold section I8 end to hingedly elign the penel strip 56 end the froni: strip 54 end bring the seet freme 53 down into resting contect With the outer section I9 end, es shown in outline in Figure 2, etop thereof. The folded structure is supported by the swing lever 26 end the breck.gt 22 end when further pushed in closing movement, swings upwerdly end inwerdly es shown in Figure 3 by the ection of the lever 26 operating ebout its pivot point end egeinst the resistence of its essocieted spring 30 Which essists in the' qpenirig movement of the structure beceuse when the bed hes been folded the spring is held weder tension. Movement of the swing lever 26 is permitted by the b1 eek of the inner section I6end the middl section I'I et their pivot point end the folding'rnovement 0f the Parts is ec-' end. its vuse in connection with an erticle of furniture is an exemple. of how it mey be employed.

My invention is not 130 be restricted to theprecise deteils of constructionshown since verious ehenges end m0dificetiolfls mey be mede therein without deperting from the scope of the invention er secrificing the edventeges derived from iI7s use.
